Charlie Sheen Hospitalized

Charlie Sheen Hospitalized: Charlie Sheen was rushed to the hospital this morning, TMZ has learned ...  and a source at the hospital tells us, "It's serious."

We're told Charlie was taken out of his home on a stretcher and loaded into an ambulance at 7 AM.

Two young women exited the house at the same time Charlie was taken out with a towel partially over his face.

Charlie was transported to Cedars-Sinai Hospital in L.A.  We're told tests were performed and doctors are waiting for results.

The 911 call was placed at 6:35 AM.

Sources say Charlie was having severe abdominal pains which triggered the 911 call. Stan Rosenfield, Charlie's publicist, tells TMZ Charlie was in the emergency room this morning -- sleeping.

We're told Charlie's father, Martin Sheen, and his mom, Janet Templeton, are at the hospital.  Charlie's ex-wife, Denise Richards, is also there.

Neighbors tell TMZ Charlie threw some sort of party last night. They heard women inside Charlie's house singing Red Hot Chili Peppers songs throughout the evening.
